ABSTRACT:
A method for fabricating a molded resinous part with a metal distributed in a surface thereof comprising: kneading a low-melting metal and a resin having a curing temperature lower than a solidification point of the low-melting metal in a molten state; and injection-molding the resulting kneaded mixture into a mold whose temperature is set to a temperature equal to or lower than the solidification point of the low-melting metal and higher than the curing temperature of the resin, thereby obtaining a molded resinous part comprising the resin as a core and the low-melting metal in a surface thereof.
